Real-Time Gas Evolution Analysis of SEI Formation in Sodium-Ion Batteries Using Chip Based Electrochemistry Mass Spectrometry

SSShivam SharmaBDBethan J. V. DaviesPRProfessor Mary Ryan

Key Points

  • This research aims to analyze the formation and stability of the solid electrolyte interphase (SEI) in sodium-ion batteries.
  • Utilized chip-based electrochemistry mass spectrometry for gas evolution analysis
  • Focused on hard-carbon anodes and their microstructure
  • Investigated the interplay between solvation chemistry and SEI stability
  • Identified key gas species evolved during SEI formation
  • Described the stability characteristics of SEI under varying conditions
  • Highlighted the relationship between SEI composition and cycle performance

Abstract

The stability of the solid electrolyte interphase (SEI) in sodium-ion batteries remains a critical challenge for achieving long cycle lifetimes. In hard-carbon anodes, the interplay between microstructure, solvation chemistry, and...
